[hobbit] hosts still disappear

Correct, beta-5, plus the patch.  

Okay, hobbitd isn't responding at all.  hobbitd.chk hasn't been updated
since yesterday, and the hobbitlog command doesn't return anything.

Strangely, no pid file was located in /var/log/hobbit.  However, a ps
grepping for hobbit showed this:

bbuser   32296 32295  0 Jan18 ?        00:00:00 hobbitd
--checkpoint-file=/opt/bb/server/tmp/hobbitd.chk --checkpoint-interval=600
--purple-conn=conn --log=/var/log/hobbit/hobbitd.log

I used gdb and attached to that pid, resulting in:

(gdb) attach 32296
Attaching to process 32296

This is with the beta-5 version PLUS the patch I posted yesterday ?

First, check if the hobbit daemon is still responding at all. You
can see if the ~server/tmp/hobbitd.chk file is being updated - it
should refresh every 10 minutes. You can also try this: If

 ~/server/bin/bb "hobbitdlog some,server,name.conn"

responds with a status log, then it is responding. If not, proceed:

Next, I want to figure out what the hobbitd proces is doing. You'll
need the gdb (GNU debugger) for that. Login as the hobbit user, Find
the process ID of hobbitd - it's recorded in
/var/log/hobbit/hobbitd.pid, or use "ps" -  then:

  gdb ~/server/bin/hobbitd
  [gdb messages]
  gdb> attach <hobbitd-processid>
  gdb> bt

Let me know what this shows.
